Head assembly of golf club

ABSTRACT

A head assembly of a golf club includes at least one various-shaped aiming mark formed in a centerline aligned with an impact line in a face of a head of a driver, an iron, or putter, or at the position opposite to the aiming mark about the centerline. Since the golfer aims when striking the golf ball, the habit of continuously keeping the golfer&#39;s aim to the head of a golf club is accustomed to the golfer such that the golfer naturally habituates the careful swing of a golf club.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a head assembly of golf clubs, and more particularly, to an improvement of a head of various golf clubs such as drivers (including fairway woods), irons, and putters.

2. Description of the Related Art

Golf is often referred to as a “mind game”, and a golfer's state of mind is of primary importance in the game of golf. Since the golfer's personality influences their golf game, it is difficult to gain skill in golf.

In particular, since a novice hastily selects and uses golf clubs and the novice may become accustomed to an undesirable golf pose, most novices have difficulty in improving their golf skills.

Generally, there are some important factors required to golfers and in playing golf games such as ‘swinging the golf club relatively slow so as to precisely drive a golf ball along a predetermined lie without failing swing form when backswinging with a golf club’, ‘minimizing cocking, i.e. striking the golf ball or swinging with a golf club only using the golfer's wrists’, ‘applying appropriate force to the golf club when using the golf club’, ‘preventing Headup (phenomenon that a golfer's head does not face impacted golf ball but is lifted up after impacting the golf ball)’, and ‘correcting rhythm and timing when swinging the golf club.’ These factors are significantly affected by the golfer's mental state to hastily swing.

SUMMARY OF THE INVENTION

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a head assembly of a golf club enabling a golfer to visually focus upon a head of the golf club and to stably aim a golf ball after striking the golf ball so as to stably strike the golf ball, to prevent the headup, and to control the backswing.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including an aim guiding device provided on a face of a head of an iron, the aim guiding device including channel-shaped aim guiding channels depressed in the face of the head such that the distance between the aim guiding channels becomes narrow as goes down.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including an aim guiding device provided on a face of a head of an iron, the aim guiding device including a colored part formed on a central portion of the face of the head by metal coloring, knurling, carbon coating, metal power coating, or the like to form an approximate V-shape

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a sight attached to a rear surface of a face of an iron and a putter, the sight being selected from a semispherical or quarter-spherical sight, a solid semispherical sight, and decorated aiming device having various shapes.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a aim guiding device provided to a face of a head of an iron, the aim guiding device including a plurality of slip lines, engraved in the form of engraved lines or protruded lines in a slip area, adjacent to a neck of the head of the iron having a lower side and connected to a head face contacting the ground when impacting a golf ball.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a various-shaped aiming face formed in a face of a head of a putter in the form of a figure, and rib-shaped aim guiding flags integrally or separately formed with the head and extending backward from the upper side of the head, and an aim guiding protrusion, as a aim guiding device, formed in the aim guiding flag in the form of various-shaped extender.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including at least one aim guiding line, converging to or diverging from an upper reference line of a face of a head of a driver, having various many-sided shapes, and formed in an upper surface of the head by engraving in intaglio or relief, or by printing a ling type print font.

In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including at least one various-shaped aiming mark formed in a center line aligned with an impact line in a face of a head of a driver, an iron, or putter, or at the position opposite to the aiming mark about the center line.

According to the head assembly of a golf club in accordance with the present invention, since mentally stable and geometric aiming is achieved, precise impact of a golf ball is achieved and the backswing and downswing of putters are slowly performed. Thus, the golfer can accustom himself/herself to desirable and considerable swinging with the golf club. Moreover, during the most important part of the putter swing, i.e. the backswing, the golfer aims the point where the golf ball is struck by the golf club, and as a result, careless swing is prevented. Thus, due to the aiming, an undesirable headup posture is also minimized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The structure and aspects of a head assembly of a golf club according to the present invention is applied to all golf clubs by various embodiments. Hereinafter, the head assembly of a golf club according to the preferred embodiment of the present invention and its modifications will be described in detail in conjunction with the accompanying drawings. Although the head assembly of the preferred embodiments of the present invention and the modifications are applied to different kinds of golf clubs, identical reference numerals are assigned to the same head and the elements corresponding to the head.

FIGS. 1 a to 1 d shows a head assembly of a golf club according to a first preferred embodiment of the present invention and its modifications.

Embodiment 1

As shown in the drawings showing only a head H of an iron I, parallel frictional lines S such as engraved lines formed in a face F of the head generate friction to prevent a golf ball from slipping.

The iron I, employing the head assembly of the first embodiment, includes aim guiding channels C1 and C2. The aim guiding channels C1 and C2 take the form of depressed channels near the sides of the face F having a channel such that the distance d between the aim guiding channels C1 and C2 becomes narrow as goes down.

FIG. 1 b shows a first modification of the head assembly according to the first preferred embodiment of the present invention. In the first modification, a aim guiding shape G is formed such as a colored part Cf is formed on the central portion of the face F of the iron I by metal coloring, knurling, carbon coating, metal power coating, or the like to form an approximate V-shape in the frictional lines S of the face F, and uncolored parts Nc1 and Nc2 as general coated metal surfaces are formed at the ends of the colored part Cf.

The aim guiding shape G, formed by the colored part Cf and the uncolored parts Nc1 and Nc2, may have a V-shape having an acute angle as shown in FIG. 1 c illustrating a second modification of the head assembly of a golf club of the first preferred embodiment, or may be formed near the lower side of the head H in the form of a V-shape. Preferably, the apex P of the aim guiding shape G is positioned on the center of gravity of the iron I.

Since the aim guiding shape G provides a high visual perception when impacting a golf ball, the golfer can aim the golf ball and precise striking of the golf ball with the iron I, and the golfer's aim can be mentally stabled and visually guided. Due to the aim guiding shape G, the golfer intend to aim the head H until the golf ball is struck by an impact point formed by the aim guiding shape G, and as a result, the habit of hastily swinging the golf club can be eradicated.

Embodiment 2

FIGS. 2 a to 2 c also show an iron I employing a head assembly of a golf club according a second preferred embodiment of the present invention having the same technical spirit of the head assembly according to the first preferred embodiment, and illustrate the iron I provided with various sights attached to a rear surface C of the face F.
